Lakhs and crores are units of the Indian numbering system commonly used throughout the Indian subcontinent. Crores are equivalent to "hundreds of lakhs" and are grouped accordingly when represented numerically. For example, 2 crores would be represented as 200 lakhs or 2,00,00,000. It can also be abbreviated to 2 cr.
1 crore (or 100 lakhs) is equivalent to 10 million. Hence, 100 crores is the same as 1,000 million or 1 billion.
